Many postmenopausal women with hormone-dependent breast cancer (requires estrogen and/or progesterone to grow) may be undertreated if they do not receive chemotherapy in addition to hormonal therapy after surgery, according to a Loyola University Health System, Maywood, Ill., study.
Loyola’s Dr. Kathy S. Albain presented the results of a 10-year follow-up of The Breast Cancer Intergroup of North America Trial 0100 at the late breaking session of the San Antonio Breast Cancer Symposium annual meeting here today. "The research shows that, in many cases, tamoxifen or other hormonal therapy alone is not optimal," said principal investigator and first author Albain, professor, division of hematology/oncology, Department of Medicine, Loyola University Chicago Stritch School of Medicine, Maywood, Ill. "Overall, chemotherapy helped stop the cancer from recurring in postmenopausal women with receptor-positive breast cancer that has spread to the lymph nodes," said Albain. "This survival advantage was greatest when tamoxifen followed chemotherapy, rather than given concurrently.
"Ten-year disease-free-survival estimates were 48 percent for those treated with tamoxifen alone; 53 percent for concurrent chemohormonal therapy; and 60 percent for sequential therapy," said Albain, director, Breast Research Program; co-director of the multidisciplinary Breast Oncology Center; and director of the Thoracic Oncology Program, Cardinal Bernardin Cancer Center, Loyola University Health System, Maywood, Ill.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
